LIFT ARRANGEMENT FOR WING OF A FOLDUP IMPLEMENT ABSTRACT OF THE DISCLOSURE Power operated means are provided to operate a foldup implement which includes a double-acting hydraulic jack interconnected between a foldup wing section and a main section. The jack has a lost motion connection with the main section permitting the wing section to float up and down about its longitudinal pivot connection to the main section during field operations. An elongated slot of the lost motion connection is so disposed as to minimize any tendency for the end of the ram associated with the slot to move from its position at the laterally outer end of the slot as the wing section is raised to its transport position, To further insure that the end of the jack will not shift from its position at the laterally outer end of the slot as the wing section is raised to a transport position, an abutment member is disposed above a part of the slot so as to abut the end of the jack in the the slot should the latter tend to shift laterally inwardly while the wing section is in its raised transport position.
